PINs don't have to be 4 digits. I use a smart card for login at work, and the PINs are required to be at least 8 digits long. The system 2-factor. The PIN is a something I know. The smart card is something I have. The PIN essentially verifies the smart card, and then the certificates on the smart card, which are much higher security, are used for everything else.

But the metadata isn't encrypted afaik. That's often more revealing than the message content. For example, if all I have is sender and receiver, I can start building relationship maps or org charts. The number of interactions between sender and receiver can indicate the importance of the relationship. If I have time stamps, I can start building a pattern of life.

There's a new version called eLORAN. It meets Stratum I timing requirements like GPS but is terrestrial based, high power, and low frequency. Basically the opposite of GNSS. eLORAN stations can be treated like pseudolites due to the precision timing, and instead of doing time difference for hyperbolic navigation it's very similar to pseudorange calculations like GNSS. So you don't need LORAN chains like before.

Comment eLORAN (Score 1) 57

This has been looked at extensively before. The conclusion was to develop an eLORAN system. But someone in DoT had a stick up their butt and kept killing it. I think Collins even developed prototype avionics tying eLORAN, GNSS, and INS together. eLORAN even meets Stratum I timing requirements like GNSS. Interesting bit of trivia. Before the Coast Guard decommissioned LORAN-C, cell towers had LORAN-C receivers as a timing backup to GNSS

Comment Every breath you take (Score 0, Troll) 102

I reminded of a song from the 80s called Every Breath You Take by The Police. I'm not a biologist, but I think every breath they take expels CO2 into the atmosphere. Will they take this to the logical conclusion and end their own lives to save the planet? Yeah, I didn't think so. Rules for thee but not for me.

People are horrible at understanding risk. Just about anything will kill you. Everytime one of these studies is published, including anything climate related, they should be required to put it into perspective. But many scientists and engineers don't even understand risk. If there's one rule of thumb that is probably universal, everything in moderation. And I'm terms of overall health outcomes, eat healthy and exercise. Eating junk and not exercising is by far the bigger problem than a little alcohol.
